Description

CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority from and is entitled to the benefit of U.S. provisional application 61/824,374, filed May 17, 2013, by Vincent P Morris. This application is related to U.S. Pat. Nos. 6,848,866, 7,008,144 7,131,787, 7,172,372, 7,554,016, 7,955,030 and 8,402,630. The entire disclosure of that application and of each of those patents is incorporated by reference herein for all purposes.
BACKGROUND OF THE INVENTION
This invention relates to assemblies and methods for installing fences, in particular, but not limited to, (i) apertured fences for controlling the movement of small vertebrates, and (ii) apertured fences for collecting sediment from sediment-containing water.
SUMMARY OF THE INVENTION
In some cases, the recommended installation of apertured fences includes creating a trench in the ground, burying the bottom section of the fence in the ground, and backfilling the trench. This method of installation ensures that there will not be a gap, either at the time of installation or subsequently, between the bottom of the fence and the ground. However, the need to make a trench is time-consuming and sometimes, depending on the terrain, difficult. This invention relates to an alternative method of securing the bottom of an apertured fence to the ground. In many cases, this alternative method replaces the installation by means of a trench in the ground.
This invention provides assemblies and methods for securing an elongate apertured fence to the ground, and fences suitable for use in such assemblies and methods. The fence includes an upper section which is apertured and which extends upwards from the ground, and a lower section which may or may not be apertured and which is not buried in the ground. The lower section is contacted by a footing member which is secured to the ground and which stabilizes the fence at a desired location. In some, but not all, embodiments of the invention, the lower section is parallel to the ground, and at least part of the footing member lies between the lower section of the fence and the ground.
In a first aspect, this invention provides an assembly which comprises
    • (1) an elongate area of ground;
    • (2) an elongate fence which extends along a line on the elongate area of ground and which comprises
      • (a) a first elongate fence portion which (i) comprises apertures, and (ii) extends upwards from the ground, and
      • (b) a second elongate lower fence portion which is not buried in the ground;
    • (3) an elongate footing member which contacts the second fence portion and stabilizes the fence along the line on the ground; and
    • (4) securing members which secure the footing member to the ground.
      Preferably each of the second fence portion and the footing member is substantially planar, and the second fence portion and the footing member are parallel to each other In many cases, the assembly also includes posts which secure at least the first fence portion in a desired position relative to the ground, the posts preferably being secured to the surface of the first fence portion which is remote from the footing member.
In a second aspect, this invention provides a method of making an assembly according to the first aspect of the invention, the method comprising the steps of
    • (A) providing an assembly which comprises the elongate fence and the elongate footing member in contact with the second fence portion;
    • (B) before or after step (A), placing the fence so that the second fence portion of the fence extends along the line on the elongate area of ground, and the first fence portion extends upwards from the ground; and
    • (C) securing the footing member to the ground.
In a third aspect, the invention provides an elongate fence suitable for use in an assembly according to the first aspect of the invention, the fence comprising
    • (1) a first elongate fence portion which comprises apertures,
    • (2) a second elongate lower fence portion which is secured to the first fence portion along an elongate line and which preferably substantially planar, and
    • (3) an elongate footing member at least part of which is secured to the second fence portion and not to the first fence portion.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is illustrated in the accompanying drawings which are diagrammatic sketches and are not to scale, and in which FIGS. 1-4 are cross-sectional side views of exemplary assemblies of the invention.
DETAILED DESCRIPTION OF THE INVENTION
In the Summary of the Invention above, the Detailed Description of the Invention, the Examples, and the claims below, and in the accompanying drawings, reference is made to particular features of the invention, including for example components, ingredients, devices, apparatus, systems, test results and steps. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular mode, aspect, embodiment, Figure or claim, that feature can also be used, to the extent possible, in the context of any other particular mode, aspect, embodiment, Figure or claim, and in the invention generally. The invention disclosed and claimed herein includes embodiments not specifically described herein and can for example make use of features which are not specifically described herein but which provide functions which are the same, equivalent or similar to, features specifically disclosed herein.
The term “comprises” and grammatical equivalents thereof are used herein to mean that other features are optionally present. For example, a fence “comprising” (or “which comprises”) a free portion and a lower portion can contain only the free portion and the lower portion or can contain not only the free portion and the lower portion but also one or more other portions. Where reference is made herein to a method comprising two or more defined steps, then, unless the context requires otherwise, the defined steps can be carried out in any order or simultaneously, and the method can include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all the defined steps. The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example “at least 1” means 1 or more than 1, and “at least 80%” means 80% or more than 80%. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number)-(a second number)”, this means a range whose lower limit is the first number and whose upper limit is the second number. For example, “0.5-3” means a range whose lower limit is 0.5, and whose upper limit is 3. The numbers given herein should be construed with the latitude appropriate to their context and expression. The terms “plural” and “plurality” are used herein to mean two or more. When reference is made herein to “a”, “an”, “one” or “the” feature, it is to be understood that, unless the context requires otherwise, there can be one or more than one such feature.
Where reference is made herein to two or more components (or parts or portions etc.), it is to be understood that the components can be, unless the context requires otherwise, separate from each other or integral parts of a single structure or a single component acting as the two or more specified components.
The term “fence” is used in this specification to denote an article which comprises a first up elongate fence portion which comprises apertures and a second lower elongate fence portion which is attached to the first fence portion and which optionally comprises apertures. In many cases, the fence includes an elongate filter component which is secured to the first fence portion, generally a lower portion of the first fence portion. The filter component optionally extends into part or all of the second fence portion. Examples of such fences are described in the US Patents incorporated by reference herein, where they are described for example as a barrier device (for example for controlling the movement of small vertebrates) or a sediment control device. Before installation of the fence in accordance with the invention, the first and second fence portions can be coplanar or at an angle to each other. In many, but not all assemblies of the invention, the first portion extends upwards from the ground and the second fence portion is at an angle, often substantially a right angle, to the first portion.
Where reference is made herein to a fence portion which is apertured, all the apertures in any particular sheet will generally be of the same size and shape, and the apertured fence portion will generally be composed of polymeric strands of the same size and shape.
The First Fence Portion.
The first elongate fence portion comprises apertures, so that the fence can provide a barrier through which wind and storm water runoff can pass but which will prevent or hinder the passage of undesirable elements, for example endangered species and/or sediment. For a detailed description of preferred fences whose purpose is to control the movement of small vertebrates, reference may be made to U.S. Pat. No. 8,402,630. For a detailed description of preferred fences whose purpose is to control the movement of sediment, reference may be made to U.S. Pat. No. 7,955,030, U.S. Pat. No. 7,544,016, U.S. Pat. No. 7,172,372, U.S. Pat. No. 7,131,787, U.S. Pat. No. 7,008,144 and. U.S. Pat. No. 6,848,866.
In one embodiment, the first fence portion is planar and extends upwards from the ground, with the lower portion of the first fence portion often being substantially vertical, for example at right angles to the ground, but sometimes as an angle to the ground, particularly if the ground is not horizontal. In another embodiment, the first fence portion comprises a first elongate planar component which extends upwards from the ground and a second elongate planar component which is at an angle, for example an angle of 20-60°, to the first component.
In other embodiments of the invention, the first fence portion comprises a threshold member having a multiplicity of relatively large threshold apertures therethrough, an elongate outflow member having multiplicity of relatively large outflow apertures therethrough, and, between the threshold member and the outflow member, an elongate filter member which has a multiplicity of relatively small filter apertures therethrough, the threshold member, outflow member and the filter being secured together, preferably being secured together so that any hollow space between them is less than 30% of the total volume of the barrier member, for example so that there is no hollow space between them.
The Second Fence Portion.
The second fence portion can be composed of a material which has the same apertures as the first fence portion, in which case, the upper and lower portions of the fence can be monolithic. Alternatively, the lower portion of the fence can be composed of a different material and be directly or indirectly attached to the first fence portion, in which case, the second fence portion can be composed of a material having apertures which are different from those in the first fence portion, or a material having no apertures.
The second fence portion, prior to installation, can be substantially coplanar with the first fence portion. In many embodiments of the invention, the first fence portion is bent at an angle to the second fence portion before or after the lower portion has been secured to the ground. However, in one embodiment of the invention, the footing member has a first part of which is secured to a generally vertical second fence portion and a second part which extends at an angle from the first part so that the second component can be secured to the ground.
When the second fence portion, when it is installed, is at an angle to the first fence portion so that it is generally parallel to the ground, its width can for example be 4 to 24 inches, e.g. 5 to 8 inches. The width of second fence portion which contacts the footing member can for example be at least 2 inches, e.g. 3 to 8 inches.
When the second fence portion extends upwards from the ground, and the footing member is, therefore, bent so that a first part of the footing member contacts the second fence portion and a second part of footing member extends at an angle away from the first part and contacts the ground, the height of the second fence portion which contacts the footing member can for example be at least 2 inches, e.g. 3 to 8 inches.
The Footing Member.
At least part of the footing member is adjacent to the ground. The ground on which the footing member is to be laid can be, but is not necessarily, smoothed before laying the footing member on it. In many embodiments, at least a first part of the footing member lies between the second fence portion and the ground. Preferably, the first part of the footing member is sufficiently flexible to conform to the ground on which it is laid, and sufficiently compressible to enable the lower portion of the fence, which may be relatively inflexible, to adapt to variations in the surface of the ground. The footing member can, for example, be a felted or other nonwoven material, or an apertured material. The thickness of the footing member can for example be 0.08 to 1 inch, for example 0.08 to 0.25 inch, or 0.5-0.75 inch. The width of the first footing member can for example be 4-24 inches, e.g. 6-10 inches.
In some cases, a first part of the footing member lies between the second fence portion and the ground and a second part of footing member lies above at least part of the second fence portion. In such cases, the two parts of the footing member can be the same or different. The second part of a two-part footing member can for example be a woven fabric, a nonwoven fabric or an apertured fabric, and can have a width which is the same as, or different from, the width of the first part of the footing member. When the footing member has two parallel planar parts, they can be secured together at an outer edge away from the second fence portion, or the two parts can be part of a length of folded fabric.
When the footing member has an upper part which is above the second fence portion, it is preferably such that the shanks of securing members (which may for example be staples or nails having a length of, for example 4 to 12 inches, e.g. 6-8 inches) can be forced through it, but the heads of the securing members do not pass through it. The securing members are secured to the ground so that the fence is stabilized in the desired location. Optionally, the footing member, the lower fence portion and the securing members are such that the conformity between the first fence portion and the ground creates at least a partial seal which prevents water from running freely under the first fence portion.
